**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Irritating to eyes, respiratory system and skin. Contact with
combustible material may cause fire.Hygroscopic.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation.
Ingestion:
Ingestion of large amounts may cause gastrointestinal irritation.
Methemoglobinemia is characterized by dizziness, drowsiness,
headache, breath shortness, cyanosis with bluish skin, rapid heart
rate and chocolate-brown colored blood.
Inhalation:
Causes respiratory tract irritation. May cause methemoglobinemia,
cyanosis, convulsions, tachycardia, dyspnea (labored breathing), and
death. Methemoglobinemia is characterized by dizziness, drowsiness,
headache, breath shortness, cyanosis with bluish skin, rapid heart
rate and chocolate-brown blood. Inhalation can cause systemic
acidosis and methemoglobinemia.
Chronic:
May cause methemoglobinemia, which is characterized by
chocolate-brown colored blood, headache, weakness, dizziness, breath
shortness, cyanosis (bluish skin due to deficient oxygenation of
blood), rapid heart rate, unconsciousness and possible death. May
cause digestive tract disturbances.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid
immediately.
Skin:
Get medical aid. Flush skin with plenty of soap and water for at
least 15 minutes while removing contaminated clothing and shoes.
Remove contaminated clothing and shoes.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Never give anything by mouth to an unconscious person. Get medical
aid immediately.
Inhalation:
Remove from exposure to fresh air immediately. If not breathing,
give artificial respiration. If breathing is difficult, give oxygen.
Get medical aid.
Notes to Physician:
Absorption of this product into the body may cause cyanosis (bluish
discoloration of skin due to deficient oxygenation of the blood).
Moderate degrees of cyanosis need to be treated only by supportive
measures: bed rest and oxygen inhalation. For methemoglobinemia,
administer oxygen alone or with Methylene blue depending on the
methemoglobinemia concentration in the blood. Cleansing of the
entire contaminated area of the body is of utmost importance.
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Strong oxidizer. Contact with combustible materials
may cause a fire. May explode under confinement and high
temperatures, especially if contaminated.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Cool containers
with flooding quantities of water until well after fire is out. For
small fires, do NOT use dry chemicals, carbon dioxide, halon or
foams. USE WATER ONLY. For large fires, flood fire area with water
from a distance.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Remove all sources of ignition. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Use with adequate ventilation. Minimize dust generation and
accumulation. Avoid contact with eyes, skin, and clothing. Empty
containers retain product residue, (liquid and/or vapor), and can be
dangerous. Keep container tightly closed. Avoid contact with heat,
sparks and flame. Avoid contact with clothing and other combustible
materials. Avoid ingestion and inhalation. Keep away from clothing
and other combustible materials. Keep away from flames and other
sources of high temperatures that may cause material to form vapors
or mists. Do not pressurize, cut, weld, braze, solder, drill, grind,
or expose empty containers to heat, sparks or open flames.
Storage:
Keep away from sources of ignition. Do not store near combustible
materials. Store in a tightly closed container. Store in a cool,
dry, well-ventilated area away from incompatible substances. Keep
away from acids. Keep away from reducing agents. Do not store near
alkaline substances.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use adequate ventilation to keep airborne concentrations low.
Personal Protective Equipment
Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to minimize
contact with skin.
Respirators:
Follow the OSHA respirator regulations found in 29CFR
1910.134 or European Standard EN 149. Always use a
NIOSH or European Standard EN 149 approved respirator
when necessary.
